In this chapter, we have had a look at the different parts of the FLORA board and how to install the IDE. We also made some small sketches to work with the on-board LED. We made our first electronic circuit using an external LED.

In the next chapter, I will introduce you to some analog sensors that are suitable for working with wearable's. We will keep using LEDs as our output, to show how we can interact with the data gathered from the sensors, as well as how to control the intensity of the LED.
